1. A façade system, comprising:
a mullion having exterior and interior portions and defining a glazing pocket between the exterior and interior portions;
a thermal break arranged within the glazing pocket and extending between the exterior and interior portions, the thermal break dividing the glazing pocket into a shallow pocket and a deep pocket larger than the shallow pocket; and
a collapsible element arranged within the deep pocket and extending between the thermal break and a lateral side of a panel introduced into the deep pocket, the collapsible element being movable between a collapsed state and an expanded state and including:
a first portion engageable with the thermal break;
a second portion opposite the first portion and engageable with the lateral side of the panel; and
opposing first and second side walls extending between the first and second portions and being foldable as the collapsible element transitions between the expanded and collapsed states, and
wherein an interior surface of the first and second side walls is engageable with the first and second portions, respectively, when the collapsible element is moved to the collapsed state and an expanded state, and
wherein the collapsible element divides the deep pocket into three thermal chambers when in the expanded state to reduce heat transfer by convection through the glazing pocket.
